Why spacetime is not fundamental

Now, we all know that spacetime is not fundamental, because physicists are saying so. But, do we know the reason why spacetime cannot be fundamental?

This is a physics question as well as a philosophy question.

If we say that X is a fundamental ingredient of the universe, then we will have to admit that whatever will exist in it, will need X for its existence. Nothing can exist without it.

However, if there is something in the universe that does not need X for its existence, then X cannot be called a fundamental ingredient of the universe.

Spaceless, Timeless, and Immaterial

1) Physicists have shown that the total energy of the universe is zero.
2) SR has shown that mass and energy are equivalent.
3) Again GR has shown that space, time, and matter are so interlinked that there cannot be any spacetime without matter; similarly, there cannot be any matter without spacetime. There is a saying of Einstein on this: "When forced to summarize the general theory of relativity in one sentence: Time and space and gravitation have no separate existence from matter."

In Defense of Emergent Spacetime

My justification for writing this post is that only emergent spacetime can ultimately lead to God. So, we must defend it in every possible way.

Recently, I have posted the following in one Facebook Discussion Group:

'Physicists are now saying that spacetime is not fundamental but emergent, and it has emerged from something non-spatiotemporal.

‘As we have come to know that spacetime is emergent, so some questions arise here that I am giving below:

God is not Purely Imaginary

God is not purely imaginary, because God has also been described as spaceless and timeless.

In this 21st century, physicists are no longer saying that spacetime is fundamental; rather, they are saying that it is emergent.

If an entity is emergent, then in general, that will mean these three things:
1) The emergent entity cannot have any existence prior to its emergence.
2) The emergent entity (A) cannot emerge from just anything or nothing; it can emerge from some particular entity or entities (B) only.
3) B must pre-exist before the emergence of A.

The Ultimate Justification for a Creator

Part I

Two reasons can be given as to why an entity may be spaceless and timeless:

1) Reason A: If the entity is not within any space and time, then it will naturally be spaceless and timeless. We can also say that it will be spaceless and timeless by default;

2) Reason B: If the entity is placed within some space and time, and if it is forcefully deprived of space and time, then also it will become spaceless and timeless.
